The United States Department of Homeland Security (DHS) is a cabinet department of the U.S. federal government with responsibilities in public security, roughly comparable to the interior or home ministries of other countries. Its stated missions involve anti-terrorism, border security, immigration and customs, cyber security, and disaster prevention and management. It was created in November 2002 in response to 9/11 and is the youngest U.S. cabinet department. In fiscal year 2018, it was allocated a net discretionary budget of $47.716 billion. With more than 240,000 employees, DHS is the third largest Cabinet department, after the Departments of Defense and Veterans Affairs. Homeland security policy is coordinated at the White House by the Homeland Security Council. Other agencies with significant homeland security responsibilities include the Departments of Health and Human Services, Justice, and Energy. Secretary Kirstjen Nielsen resigned on April 7, 2019, effective April 10. By law (6 U.S.C. §113(g)), Undersecretary for Management Claire Grady was to become the acting Secretary of Homeland Security. On April 7, President Donald J. Trump designated the current U.S. Customs and Border Protection Commissioner Kevin McAleenan as acting Secretary; that had lingering questions of legality resolved after Trump forced Grady to resign on April 9. McAleenan then named David Pekoske, who currently also serves as the TSA Administrator, as the acting Deputy Secretary. On November 13, 2019, Chad Wolf became the Acting Secretary and named Ken Cuccinelli as the Acting Deputy Secretary.
